the weight of evidence
no sources on either side

Gravitational slingshots are a well-established orbital mechanics technique where spacecraft gain or lose velocity relative to planets, requiring no citation as common scientific knowledge.

The analysis

The claim is a fundamental, well-known principle of orbital mechanics and celestial mechanics (gravitational assist/slingshot maneuver) taught in introductory physics. None of the retrieved papers specifically target or test this exact commonplace mechanism, making it common knowledge where citations are unnecessary.
